DO NOT run it on a 1.1.2 iPhone. I tried it, and all it does is semi-brick your iPhone. It still turns on, and you can access recovery, but it fails basically. If you already have, PM me, and I'll help you unbrick it. It takes somewhat fast pressing of icons to do it though.

This has been done in many threads / forums. It would be best to put 'upgraded 1.1.2' so you will not mislead people thinking it's OTB. A lot of people (like me) are waiting for it and don't want to waste time going through threads to find out it's another 1.1.2 upgraded thread.
